Intel Pentium P6100 Vs Dual Core T4500 comparison, difference

Both the Intel Pentium P6100 and the T4500 are dual core processors. The Pentium P6100 is based upon the newer Arrandale architecture ( pretty much similar to the core i3 architecture) while T4500 is based upon older Penryn architecture.

The Pentium P6100 is clocked at 2.0 GHz while T4500 is clocked at 2.3 GHz. It gets really difficult to tell which of these two processor are faster without looking at the real benchmarking numbers. But, before we do that, we would like to point out some of the architectural differences between the two processor.

– The Pentium P6100 has integrated memory controller. The processor communicates with the memory directly, with no middleman involved in between. In case of the Dual core T4500, the processor first communicates with a north Bridge – “the middleman”, who in turn communicates with the Memory. This slows down the processor to the memory communication speed in T4500.

– The L1 Cache structure is same for both the processor. However, the arrangement of the L2 and L3 Cache is different. The Pentium P6100 has 3 MB of shared L3 Cache, that Intel calls smart cache ( in addition to 512KB of L2 Cache). The T4500 has 1 MB of L2 Cache. The Cache memory is another factor that leads to improved performance in case of the P6100.

– The Pentium P6100 has integrated graphics controller, which is useful in design of simpler and low cost system. The T4500 does not has any integrated graphics controller.

– The T4500 however has 2.3 GHz clock frequency, which makes up for many of the shortcomings.

With this background, let us see the benchmark number to find which processor is better.

– The Super Pi 2M takes 50 seconds with the Pentium P6100 while it takes close to 63 seconds in case of T4500 processor. This proves supremacy of the Pentium P6100 – and yes – even with slower 2.0 GHz clock.

– The 3D Mark06 CPU score for Pentium P6100 is 1840 while that of the Dual core T4500 is 1900 implying a tie in the performance.

– The CPU benchmark score for T4500 is 1573 Vs P6100’s score of 1525.

From the comparison, it is clear that P6100 gives a tough fight to T4500 even with lower frequency. We can therefore expect that P6200 ( clocked at 2.13 GHz) should definitely overpass T4500 in performance.

The Pentium P6100, however, can be a better choice because, it has integrated memory controller, which reduces overall system cost. In memory intensive computation, the larger L3 Cache and the integrated memory controller, comes to definite advantage for Pentium P6100
